Narrative of Process Areas that Contribute Wastewater to Treatment Process
Thomas Concrete of Carolina, Inc.
Smithfield, NC
1. Cement Truck Cleanout Area
Vehicle cleaning activities are conducted in the slump rack and washout pits in the western portion of the
property in a designated area northwest of the office building (see Sheet 2). General vehicle cleaning
activities are conducted on a 20-ft x 100-fl concrete pad on the northwest side of the site. Cleaning
chemicals are stored in a 55-gallon drum and 300-gallon totes adjacent to this pad or near the slump rack
west of the office building, and metered into dispenser nozzles for spray application onto the trucks.
Wastewater from the vehicle cleaning process flows into a series of three settling pits and a wastewater
collection and treatment system located on the northwest corner of the property. Solids are removed from
the wastewater through settlement within the pits. The settling pits are each 12 feet in width, 80 feet in
length, and five feet deep, with bottom slopes of 6% and have approximately 2,880 square feet of surface
area. The settlement pits provide approximately 7,200 cubic feet (53,860 gallons) of secondary containment
volume for collection of wastewater generated from the vehicle washing process and stormwater runoff flow
from the surrounding impervious area. The water contained in the pits gravity Mows into a retention basin
southwest of the settling pits, and is pumped back into the vehicle washing process and slump rack by a
sump pump and three-inch rigid and flexible piping installed overhead. Solids are periodically removed
from the pits with a front-end loader and transferred to a holding area on -site, where they are de -watered
and transported off -site for disposal at a C&D landfill facility.
The retention/recycle basin measures 140 feet by 27 feet by 6 feet deep, and has a capacity of approximately
6,617 cubic feet (49,500 gallons) with one foot of freeboard provided. Overflow from the retention/ recycle
basin discharges through a rip -rap -lined emergency overflow structure and into a vegetated filter strip
installed on the western property line. Flow control components for the recycle line in the retention basin to
the cleaning process include a pump and manual ball valve.

North Carolina's Sedimentation Pollution Control Act is performance -oriented, requiring
protection of existing natural resources and adjoining properties. If, following the
commencement of this project, the erosion and sedimentation control plan is inadequate to meet
the requirements of the Sedimentation Pollution Control Act of 1973 (North Carolina General
Statute l 13A-51 through 66), this office may require revisions to the plan and implementation of
the revisions to insure compliance with the Act.
Acceptance and approval of this plan is conditioned upon your compliance with Federal and
State water quality laws, regulations, and rules. In addition, local city or county ordinances or
rules may also apply to this land -disturbing activity. This approval does not supersede any other
permit or approval.
Please note that this approval is based in part on the accuracy of the information provided in the
Financial Responsibility Form, which you provided. You are requested to file an amended form
if there is any change in the information included on the form. In addition, it would be helpful if
you notify this office of the proposed starting date for this project. Please notify us if you plan to
have a preconstruction conference.
Your cooperation is appreciated.
